Because of the holidays, we're needing to do some maintenance on our AS400 in a much smaller window then we are used to, Normally, we can set aside close to a 24 hour window on a Sunday when we need to do any maintenance that requires taking our AS400 offline, but, this evening, we're limited to about a 6 hour window. Our service provider has warned us to expect up to a 3 hour window for the work that we're having done, but we also need to do a full system save before taking the system offline, which could add another 3 hours to the process. To prepare for the work tonight, I'm doing some last min clean up of our system, and deleting a lot of records out of our test, and dev systems, as well as cleaning up some redundant/unneeded records in our live environment.
My question is, as far as speeding up the save, will simply deleting the records speed things up, or will I also need to run a reorg to compact the files? I think that the save will only save active records, and will trim out all of the deleted records, but, I didn't want to make an assumption that could cost us a half hour of our 6 hour window.
